why are coastal areas densely populated

why are coastal areas densely populated

Coastal regions also provide critical inputs for industry, including water and space for shipping and ports; opportunities for recreational activities such as fishing and diving; and other raw materials, including salt and sand. Unless governments and users of coastal resources take action, population pressures and the associated levels of economic activity will further degrade many coastal habitats.

Using data from scores of stations around the world, scientists can calculate a global average and adjust it for seasonal differences. Population, density and education all play a role. Photograph by Indumathi Govindasamy, My Shot. Moreover, the ships provide few long-term economic benefits for the local population, since they do not employ many local citizens. Waiyaki Way Cassia House, Ground Floor Stretching inland from the Gulf Coast, the Coastal Plains, encompassing about two-fifths of the state’s land area, range from sea level to about 1,000 feet (300 metres) in elevation.… It can be used as a statistic to show how many people live in that specific area. Coastal zone management Some 37 per cent of the world's population lives within 100 km of the coast, at a population density twice the global average. All of these people have an effect on the health of the ocean. Today, approximately 3 billion people — about half of the world’s population — live within 200 kilometers of a coastline. Nondemographic factors, including the economy, national and local policies, technology, and culture, interact with population changes to affect the natural environment. Since 2000, Save the Children has been implementing the People and Environment Coexistence Development Project (PESCO-DEV), working with 12 coastal fishing communities in the Philippines to find ways to balance activities linked to population growth and environmental concerns through participatory research, community mobilization, and pilot projects. If needed, have students explain what their drawings show. Buccoo Reef, a marine park in Tobago, is the Caribbean island’s largest, shallowest, and most accessible reef; as such, it is of immense value to the tourism industry. The reef is also threatened by inadequate treatment of sewage in the surrounding area. Poor women depend especially heavily on fish and fishing. UNEP, “Tourism’s Three Main Impact Areas” (Oct. 9, 2001), accessed online at www.uneptie.org/pc/tourism/sust-tourism/env-3main.htm, on Aug. 14, 2003. The arrival of new fishermen, together with the introduction of new fishing techniques and increased access to credit and markets, has contributed to the overexploitation of sea cucumbers in the region.10. Breaking the marine food chain reduces vital supplies of protein for about 1 billion people, most of whom live in developing countries.27, Yet restricting fishing rights and access to coastal waters in order to project marine fauna may harm vulnerable groups of people. Sustainability Policy |  The average population density in coastal areas is about 80 persons per square kilometer, twice the world’s average population density. The NE of Brazil is sparsely populated inland but is densely populated at the coast. This activity targets the following skills: The resources are also available at the top of the page. ICM has been endorsed repeatedly in international conferences, including the 1992 UN Conference on Environment and Development in Rio de Janeiro, Brazil, and the 2002 World Summit on Sustainable Development in Johannesburg, South Africa. Philomene A. Verlaan, “The Importance of Coastal Management to Human Health,” in, World Bank Group, “Sewage Disposal Project Transforming Urban Environment and Improving Quality of Life in Mumbai, India” (1999), accessed online at http:// lnweb18.worldbank.org/sar/sa.nsf/, FAO, “Coastal Zone Management and Equality Between Women and Men” (1998), accessed online at www.fao.org/sd/epdirect/. Tourism, fishing, and aquaculture are industries with major economic influences on coastal ecosystems. 3362 days since Next Geography Class!!! The Latin American areas of high population concentration include the central part of Mexico, where nearly half the nation’s population … But the combined effects of booming population growth and economic and technological development are threatening the ecosystems that provide these economic benefits. Have students draw pictures that illustrate why people live near coasts. Sea level is measured by two main methods: tide gauges and satellite altimeters. The Northern Plains of India are densely populated due to the fine alluvium deposits which makes the plain very fertile. Tourism, Tobago’s largest employer, relies on a healthy marine environment and especially on the health of Buccoo Reef. By discharging ballast water near the islands, large vessels and smaller fishing boats have introduced nonindigenous plant and animal species to the islands’ coasts.9 The situation in the Galapagos Islands also highlights how migration can contribute to the depletion of natural resources. Explain to students that darker areas indicate greater population density, which measures how many people live in a square mile. Consequently, many coastal nations have experienced rapid uncontrolled development along their coastlines. Ask students to describe the patterns they see. Urban Boundaries. When concentrated in small, confined, and overcrowded areas such as coastal zones, pollution and other problems pose greater threats to human health. This is a concern because population growth and the activities associated with it can degrade coastal and marine ecosystems.3 A number of worrying trends are already visible. Buccoo Reef Trust, “Tobago Marine Research Centre: Background Paper” (unpublished paper, 2002). The Caribbean Coastal Marine Productivity Programme (CARICOMP), a regional network of marine laboratories, parks, and reserves that studies land-sea interactions, strives to identify which changes in coastal systems are caused by human disturbances and which are simply long-term natural variations. In fact, 14 of the world’s 17 largest cities are located along coasts. Eleven of the world's 15 largest cities lie along the coast or on estuaries. R. Layng, “Strengthening Formative Environmental Research Through the Inclusion of Population Variables,”. All three cities are densely populated and, while the nature's way of getting rid of pollution is through rains and long-lasting strong winds, the cities receive neither of the two. The problem is particularly acute in developing countries. It can lead to unsustainable coastal development as infrastructure is built on the shoreline to accommodate tourists. The figures in China and Southeast Asia are staggering: 1,000 people arrive in China’s large coastal cities each day, and similar numbers move to the coasts in Vietnam and the Philippines. In the Caribbean, official estimates say that 70,000 tons of waste are generated annually from tourism activities.17 Yachts, charter boats, and cruise ships are major sources; they bring visitors to ports that often have inadequate collection systems for dealing with the solid waste discharged by the ships. That is why for example that Saudi Arabia is recorded as having a higher population density than the Netherlands, because the built-up area of Saudia Arabia has a higher density of people despite the country including the vast Arabian Desert. Rainera L. Luero and Robert Layng, “Understanding Reproductive Health/Natural Resource Management Integration in the Philippines,”. Then explain to students how they can tell where many people live and where few people live. Multiple stakeholders, including representatives from all levels of government, NGOs, indigenous groups, communities, and the private sector; A strong scientific foundation to inform the management process; A formalized mandate and funding mechanisms; Formal decisionmaking that incorporates social, environmental, and economic data; Public participation starting at the initial stages of policy formulation and program development; Community-based management initiatives to develop community experience, build support, and provide information about regional or national programs; Capacity building of local experts through training, education, and applied research; Strong outreach services that provide information and education to all levels of management; and. Maintaining a healthy coastal habitat is critical because most of the world’s fish produce their young inshore and feed on organisms in coastal waters. NOAA Office of Ocean Resources Conservation and Assessment (ORCA), “ORCA’s Coastal Assessment Framework,” accessed online at http://spo.nos.noaa.gov/projects/caf/caf.html, on June 30, 2003. ICM attempts to forge a balance between users of water and natural resources while ensuring that long-term environmental health and productivity are not compromised.32 Countries may use ICM to address the depletion of coastal and ocean resources; deal with pollution that endangers public health; distribute the economic benefits of using the coast and ocean; or develop and manage coastal and marine areas that are not yet being exploited. Coral reefs worldwide are deteriorating at an alarming rate: As of late 2000, 27 percent were severely damaged, compared with 10 percent in 1992.2 More reefs are degraded and threatened by dynamite fishing, coral mining, and other human activities, as well as by bleaching caused by rising ocean temperatures. The most densely populated parts of the US are found in major metropolitan areas around the states of New York, New Jersey, California, and Connecticut, among others. POPs tend to linger in living tissue and become more concentrated as they move up the food chain, so they are sometimes found even in people who live in remote, undeveloped regions. Bathing in or ingesting sewage-contaminated water can cause infections and transmit diseases such as cholera, particularly among children under 5.22 In developing countries, more than 90 percent of wastewater and 70 percent of industrial wastes are discharged in coastal waters without being treated. Students calculate population density in the United States and describe some of the patterns in the results. But tourism can also have harmful effects (see Box 1). Many of the world’s coasts are becoming increasingly urban. Geography!!! Malé, Island (divisions Henveiru, Galolhu, Machchangolhi, Maafannu), Republic of Maldives. The average population density in coastal areas is about 80 persons per square kilometer, twice the world’s average population density.7 Up to 50 percent of the population in northern Africa and Bangladesh lives in coastal areas; along the Nile Delta, the population density reaches 500 to 1,000 people per square kilometer.8 The additional demands that high population density places on the coasts have meant that higher density is associated with increased risks to marine ecosystems. 2. Population density is a ratio of the average number of inhabitants per square kilometre. Email: PRBKenya@prb.org, © 2020 Population Reference Bureau. It is worked out by simply dividing the population by the area of the Federative Units.In 2014, Brazil had an overall population density of 24.66 inhabitants per square kilometer. Global warming will likely be accompanied by sea level rise. The reasons for environmental decline are complex, but population factors play a significant role. The Rights Holder for media is the person or group credited. This policy brief looks at how population growth, urbanization, and other factors affect coastal resources; how environmental degradation influences people’s lives; and how policymakers can integrate population and resource management issues. 3. Have students brainstorm and draw why people might choose to live near the coasts. Fishing or harvesting, the destruction of mangroves, and pollution and sedimentation from human activities all can affect the coastal environment. Addressing population issues is key to achieving such balance. Students should recognize that many more people live near the coasts than inland, although the Great Lakes and a few places in the interior, such as Atlanta, Georgia, are densely populated. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. Ask: Is it in an area that has many people? Sitemap. Many coastal areas are densely populated, but a large expanse of coastal areas are hardly populated at all. Coastal areas with high population densities are those with the most shoreline degradation or alteration. At the same time, they are more densely populated than the hinterland and exhibit higher rates of population growth and urbanisation. Phone: +254 735 084293 The high nutrient content of wastewater discharged into Buccoo Bay and other waters adjacent to the reef has spurred rapid growth of algae, which damages the reef.4 High levels of fecal coliform bacteria, which pose a threat to human health, have been measured on certain beaches in the park, indicating that the water has been contaminated with human or animal feces.5, Box 2 Changes in the size, composition, and distribution of human populations affect coastal regions by changing land use and land cover. Since the early 1990s, sea level has been measured from space using radar altimeters, which determine the height of the sea surface by me… Privacy Notice |  But higher population densities may have beneficial effects as well: As population grows, some governments make greater investments in infrastructure such as sewer lines and sewage treatment plants that ultimately reduce levels of environmental contamination. Other articles where Coastal Plains is discussed: Texas: Relief: …the fertile and densely populated Coastal Plains in the southeast to the high plains and mountains in the west and northwest. Manuel Benítez et al., “A Platform for Action for the Sustainable Management of Mangroves in the Gulf of Fonseca” (November 2000), accessed online at www.unesco.org/csi/wise/fonseca1.htm, on Aug. 14, 2003. If all coastal areas were populated at equal density this curve would be a straight line.According to this analysis, 40% of the near£oastal population occupies about 4% of the nearcoastal land area at local population densities greater than 1000 people/km2.The most densely-populated near-coastal areas are in Europe and south, Contaminants and activities that destroy coastal habitats and ecosystems also contribute to the loss of the marine fauna on which many people rely for food and income. Several strategies can be used to incorporate population and gender dynamics in planning project activities: In the Philippines, for example, projects have used a combination of these models to build links across sectors. So I think you meant to compare coastal areas to interior areas. The most serious concerns worldwide involve persistent organic pollutants (POPs), which can be transported in the atmosphere and have become common in the oceans. How might global warming exacerbate coastal hazards? Encourage students to think about how people move (transportation routes), weather, and climate. In the United States, around 53% of the population lives near the coast. Baseline studies assessing the threats to coastal areas should include data on population and the environment, indigenous peoples’ concerns, applicable legislation and the agencies involved, gender concerns, and socioeconomic characteristics of the areas. Second, staff used geographic information system maps to compare data on population and land use for the past 50 years. Brazilian states by Population Density, in people per square kilometer. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. With one birth every 7 seconds, a death every 13 seconds, and a migrant entering the country every 31 seconds, the United States’ population is growing at a rate of one person every 11 seconds. This information is targeted to those who influence policy, such as policymakers and their advisers, the media, and nongovernmental organizations. Eighty percent of marine pollution comes from land-based sources; the remaining 20 percent comes from atmospheric sources, including acid rain and marine-based sources such as oil spills.21 As coastal communities grow, sewage can become a threat to local waterways: Demand often exceeds available sewage treatment, and much of the sewage is dumped without being treated. NG MapMaker Interactive: Population Density—United States, How People Affect Ocean Animals and Plants, identify patterns of human settlement on a United States population distribution map, brainstorm and draw possible reasons so many people live near the coast, Tech Setup: 1 computer per classroom, Projector. These studies can be conducted using either exhaustive research or rapid assessment techniques. Bénitez et al., “A Platform for Action for the Sustainable Management of Mangroves in the Gulf of Fonseca.”. These fishermen sometimes unknowingly exacerbate a problem created by tankers and ocean liners. It also involves improving the exchange of data between the science and management communities and focusing more on demographic and socioeconomic factors that contribute to marine pollution and coastal degradation. If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher. Many species are overharvested because the world fishing fleet is larger than it needs to be. United Nations Development Programme (UNDP) et al.. United Nations Food and Agriculture Organization (FAO), Sara Curran et al., “Interactions Between Coastal and Marine Ecosystems and Human Population Systems: Perspectives on How Consumption Mediates This Interaction,”, United Nations System-Wide Earthwatch, “Oceans and Coastal Areas,” accessed online at http://earthwatch.unep.net/oceans/. The northern region includes the 7 states and union territories of Jammu & Kashmir, Himachal Pradesh, Punjab, Chandigarh, Haryana, Delhi and Rajasthan and has a population density of 267 persons per sq km as per the 2011 C… When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. Worldwide, sewage is the largest source of environmental contamination, and discharges have increased dramatically in the past three decades. Or is it in an area that has few people? Privacy Policy, Ripple Effects: Population and Coastal Regions, U.S. 2020 Census and American Community Survey, American Community Survey (ACS) Data Users Group, PACE (Policy, Advocacy, and Communication Enhanced). If not properly managed, development can result in pollution, deforestation, and inadequate management of soil, water, pesticides, and fertilizers. The main cities in the Southeast include Sao Paulo and Rio de Janeiro. In spite of this widespread concern over sea level rise, no accurate worldwide estimate of the number of people likely to be affected by coastal inundation or flooding has been published. After Mongolia, Namibia is the second least densely populated country in … Have students locate where they live. Liz Creel prepared this policy brief with assistance from PRB staff and other colleagues. Efforts to balance local interests with national legislation need to consider the socioeconomic context of coastal populations and what role demographic patterns play in the region. Show students the NG Education interactive map. Incorporate Population and Gender Dynamics Into Planning. Point out the East Coast and West Coast. Is South Africa densely populated? You cannot download interactives. Hence,many farmers prefer to settle here, people also settle here as it is the bestlandformto settle on and it has the most facilities like transportation, communication etc. (Northern Siberia, Northern Canada, most of Australia's coast, etc.) The project used a three-stage approach to identify and address population changes that affect fishing in the area. Students describe crowded and uncrowded places, brainstorm possible reasons for crowding, and brainstorm good and bad things about living in a crowded place. Videos and links. They also provide food, building materials, shoreline protection, and many indirect benefits for people living near them. Students look at a map of population density in the United States, describe the pattern of settlement they see near the coasts, and brainstorm and draw possible reasons for it.
